You won't see such iconic things as the Ark of the Covenant, but that doesn't mean Warehouse 13 won't contain a bunch of cool objects just ripe with storytelling potential. One wing of the facility, for instance, acts as a containment sector for the Hitlers of the world we never knew about. One of the most interesting items is the Looking Glass from Alice In Wonderland.

"I would have to say that my favorite episode so far has been Lewis Carroll's mirror, probably because it was the biggest acting challenge," Joanne Kelly told reporters in a recent conference call. "It was a huge challenge, and it was a lot of fun. I got to kick up my heels a little bit. So that's probably been my favorite, along with the fact that I'm such a Lewis Carroll fan and have been for years and years. ... Through the Looking-Glass and [Alice's Adventures] in Wonderland are two of my favorite books, so that was really kind of special."
